Aquatica, SeaWorld's Waterpark, Orlando

Ihu's Breakaway Falls at SeaWorld's Aquatica is billed as the tallest and steepest waterslide in Orlando, sending thrill-seekers 40 feet straight down before they twist and turn their way through the colorful slides. Race headfirst against 7 other guests on Taumata Racer, a high-speed racing slide, or wind down at the park’s lazy river. The popular wave pool and the splash fortress with a 500-gallon dumping water bucket will please even the smallest park guests.

Six Flags Magic Mountain, Los Angeles

For a twisted new ride this summer, hop on the Twisted Colossus. According to Six Flags Magic Mountain, it has 5,000 feet of wood and steel track, making it the longest and most innovative hybrid coaster in the world. But Trip Flip host Bert Kreischer’s favorite ride in the world is Magic Mountain’s Superman: Escape From Krypton. “I spent the entire summer shooting a series for Travel Channel at this park, and every single day at sunset, the entire crew and I would meet at the 415-foot tower for 1 last ride before the park closed,” he says.

Six Flags White Water offers fun for all ages, with rapids, twisters, free falls and tube rides, plus 3 kid-friendly zones — Captain Kid’s Cove, Lilypad Crossing and Tree House Island — with the oh-so-fun water-dumping buckets and splash play areas. This summer, the park is unleashing Dive Bomber, which drops brave riders through a trapdoor for a zero-gravity, 10-story, heart-stopping fall. If guests prefer more chill than thrill, White Water offers cabanas for families to relax and escape from the sun.

Wet ’n’ Wild Hawaii, Kapolei, HI

A trip to Oahu must always be accompanied by a visit to what might be one of the best water parks in the country, Wet ’n’ Wild Hawaii. The new Waimea Whirl, set to open this summer, is among several water thrills packed into the 29-acre park, which competes with some of the world’s best beaches. Shaka — a favorite ride of Bert Kreischer, host of Travel Channel’s Trip Flip and Bert the Conqueror — has a 2-person inner tube plummeting down more than 4 stories, and the ride doesn’t end until gravity and inertia are done with you.
